CHARLES BURNHAM, OF LGS ANGELES, CALIFORNIA, ASSGNOR TO BURNHAM BASKETCOlJPANY, [i CORORA'IIN OF CALFORNIA.

BOX-AKING MACIINE.

Application filed February a, 1915.

To all 't0/1.0m 'it 'may Concern Be it known that I, CHARLES BURNHAM, acitizen of the United States, and a resident of Los Angeles, county ofLos Angeles and State of California, have invented certain new anduseful Improvements in Box- Making Machines, of which the following is afull, clear, and exact description.

This invention relates more particularly to the punch and die mechanismof a machine for making berryl or fruit baskets such as shown in mypending application, Serial No. 734,155, filed November' 29, 1912.

One of the principal objects of the invention is to provide meanswhereby shocks of veneer or other material may be supported crosswiseand folded into box form without the necessity for scoring the shocksand without causing or permitting the shooks when of wood to break orsliver at the point of folding particularly where the shocks,

as is often the case, are cross-grained, and

which means during the folding operation will move the box body in itsfolded form in position to receive ametal or other suit able binding tocomplete the box.

Another object of the invention is to provide yieldingly held wings as apart of the die mechanism and which so co-act with other parts of thedie that during the folding the shocks or body material will bepositively held at the point of folding and the wings made to lap orslide at such fold ing point, thus making a perfect fold.

Other objects of the invention are to provide the die with yieldingparts which will compensate for any error in lengths of the shocks andwhich will feed the shooks if of uneven lengths properly into thebinding rim and hold the same while the bottom of the basket takes careof the error in the difference in lengths of the shocks and still allowa good basket to be made; to provide simple means for absorbing theinaccuracies in alinement and also any difference in the thickness ofthe wood or other shocks; and to provide adjustments between the severalparts of the die mechanism and to hold the same againstl impropermovement.

A further object of the invention is to provide a simple and effectiveplunger or punch which is adapted to cooperate with the die, and whichassists in forming the box body Specification of Letters Patent.

Serial No. 6,109.

and further assists in stripping the box body when formed.

A still further object of the invention is to provide simple meanswhereby parts of the plunger or punch mechanism may be removed forrepairs or for other purposes.

A. still further object of the invention is to provide simple andeflicient means whereby suction may be created or destroyed in a part ofthe die to assist in stripping the box when formed from the punch andkeep the box down in the die and place the same in position for removalfrom the machine.

A still further object of the invention is to provide simple andeflicient means for holding the shocks crosswise for removal and foldingby the punch and die.

l/Jith these and other objects in view, the invention will behereinafter more particularly described with reference to theaccompanying drawings, which form a part of this speciiication, and willthen be pointed out in the claims at the end of the description.

In the drawings, Figure 1 is a vertical section, partly in elevation, ofone form of punch and die and mechanism embodying one form of myinvention and showing a shook holder or carrier located between thepunch and die for supporting the shooks crosswise of each other. Fig. 2is a fragmentary vertical section showing one form of means for creatingsuction in the die. Fig. 3 is a view similar to Fig. 2 except that theparts are in a different position. Fig. i is an enlarged verticalsection, partly broken away and partly in elevation, of the die andmechanism shown in Fig. l. Fig. 5 is a fragmentary section showing aform of adjustment between certain parts of the die mechanism. Fig. 6 isa fragmentary side elevation of the adjusting means shown in F i 0. 5.Fia'. 7 is a vertical section taken on the line VII-VII of Fig. 5showing how the adjustable links are held spaced apartin pairs. Fig 8 isa plan view, A, artly in section and partly broken away, of the die andits mechanism and the guide frame for the die. Fig. 9 is a sectionalplan taken on the line IX-IX of Fig. 4. Fig. l0 is an enlarged verticalsection, partly broken away, showing the punch or plunger and the die inposition after the shocks have been folded into box form, the positionof some of the parts being' somewhat exaggerated for illustrativepurposes. Fig. is a fragmentary section showing how the mechanism may bemade to clench the metal rim or binding to the box form with adovetailed effect. Fig. 11 is a vertical section of the punch showingthe means for operating the same as well as the mechanism for pinchingthe binding` about the box form. Fig. 12 is an inverted plan view of thepunch or plunger. Fig. 13 is an enlarged view, partly broken away andpartly in section, showing the clencher mechanism. Fig. 14 is anenlarged fragmentary section of the punch and parts in their normalposition. Fig. 15 is a fragmentary section of a part of the punch orplunger. Fig. 15a is a fragmentary sectional plan showing how two screwsof the punch may be held from turning. Fig. 1G is an inverted plan ofthe punch and clencher mechanism partly broken away. Fig. 17 is a viewof a spring clip or latch for the metalbinding. Fig. 1S is a fragmentarysection, partly in elevation, of a fixed form of latch or catch forholding the lapped. ends of the binding prior to Vclenching the same tothe box form. Fig. 19 is a fragmentary elevation of the form of latchshown in Fig. 1S; and Fig. Q0 is an inverted side elevation of the camportion on one of the clenching members which is adapted to depress oneof the folders for the metal strip while the strip is being forced aboutthe anvil or former.

lliile the invention is ordinarily applied to a particular form ofmachine, it will be understood that many of the features may be used inconnection with various forms of box or basket machines or alone, andthat some of the parts may be dispensed with or other featuressubstituted therefor without departing from thc spirit of the invention.

In the general operation of an automatic box-making machine to whichthis invention is particularly applicable, a narrow metallic strip isfed from a reel or other wise suitably supported convenient to themachine, and this strip by suitable mechanism is fed to what may betermed forming mechanism, that is, the metal is bent or formedlengthwise thereof so as to be substantially V-shaped or U-shaped incrosssection in order to lit over the open edge of the box form. Thisstrip is fed inward and tilted and after being tilted so that it willassume a proper position relative to the edges of the box and the anvilor former about which it is bent according to the shape of the box, thestrip is then cut off the proper length. The strip is then fed forwardon one side of a substantially rectangular anvil having a shapecorresponding to the shape of the open end of the box and luntil thesaid strip meets the anvil,

when the jaws into which the strip has been previously fed by engagementwith the former or anvil will bend both ends of the strip on oppositesides thereof making the same substantially U-shaped. A. second pair ofjaws engages the free ends of the binding strip and forces the same onthe remaining side of the anvil and causes one end of the strip tooverlap the other. The shooks of which the box body is made are placedin two magazines located adjacent to one end of the machine, and theseshooks are automatically fed upward in position to be removed therefrom.A reciprocatory and rotary pneumatic device is provided for this purposeand this device is automatically controlled so that the shooks will bepicked up lirst from one magazine and then from the other so that theshooks as thus picked up will lie crosswise and at substantially rightangles to each other. The pneumatic device discharges the crossed shooksinto a rotary carrier or turret. A movement is given to the carrier andthis places the crossed shooks in the path of box-forming mechanism, andat the proper time this mechanism operates to form the shooks into boxform and carries the box from above the carrier and forces the upperedge thereof into the binding strip. The -bind ing strip is then pinchedon to the shooks thus holding the box shooks permanently together in boxform. Means is provided for stripping the box and 'causing the completedbox to be deposited into the carrier, and the carrier as it feeds newshooks crosswise to the die mechanism conveys the completed box intoposition to be discharged. The completed box is forced out of thecarrier into a chute and properly stacked and may be removed in anydesired way. jinother form of machine to which the invention isapplicable is one in which two or more strips are used as a binding' foreach box or basket, or as already stated, the invention may be usedsimply as a hand operated or box body forming machine.

rlhe veneer-shooks are placed in a holder 1() in any suitable waybetween a punch or plunger 11 and the die 19.. The holder if) may be ofany suitable kind or may bein the form of a carrier which is adapted tomove the shooks in a crosswise position under the punch 11 and then toreceive the completed box and move the same away from the punch and diein substantially the manner described in connection with the applicationhereinbefore referred to. 1nstead of the movable holding means for theshooks as set forth in said application for holding' and alining thesame, the' said shooks ,maybe sprung or forced between stationarygrippers 13 and 14C. There are two substantially L-shaped grippers 13and two similar grippers 14C arranged in opposed relation and eacli hasa retaining lip or bead 14a. rl`he sets ot grippers 13 and 1l are. soarranged that When the shooks are forced therein they Will lie one at ahigher level than the other so that any diiierencc in their lengths willnot cause the top shook to spring the one beneath it down so tar thatthe latter will be away irom its regis# tei-ed position in thegripper-s. rl`hese shoohs are indicated at 15 and 1G and are adapt-ed,as will be hereinafter described, to be held between the plunger and dieand to be moved by said plunglr and die ,trom the holder 10 and formedinto box form.

The die and its operating mechanism, Figs. 1 and il to 111-, comprises ahead 17 substantially rectangular' in. form and having a concaved uppersui-tace in which is seated a rubber gasket or pad 18 also substantiallyrectangular' in form. rThis pad is held by a plate 19 which extendspartly over the upper surface or" said pad. The plate 19 has a centralopening and through said opening extends a tubular reiv 20, the threadedend of which engages the threaded upper opening of a tubular member 21in which suction may be created or a vacuum formed so as to createsuction about the pad 18 as will be presently described. The screnT Q0Well as the upper surface ott the plate 1Q are each provided withvradiating grooves adapted to communicate with the tube or member 21 sothat suction may be created over substantially the entire surface otsaid suction pad 18, Ait the outer edge of the pad 18 are yieldingmembers rllhere are tour of such members so as to make a substantiallyrect-angular body When in position which corresponds substantiallyT tothe shape ot the boi; or berry basket bottom. rllhese members aresubstantiallyT L- shaped in form and have one portion thereot movable inrecesses 23 in the die head 17 and said members 22 are normally forcedoutward by springs 34-, located in said recesses 23, the outwardmovement oi said members being limited by means oiE screws Q5 or in anyother desired Way. rllhe purpose ot' these yielding members 22 is tocompensate tor any irregularity in the length o't the shooks wheninserted into the binding as will be described hereina'tteiu the saidplates or members 22 yielding su'liicientlv to permit the sides of thebox when 't'olded to be 'forced slightly downward in order that theupper edges ot the box may be substantially straight and in order thatthe narrow metal binding may be properlv held to the upper edges of theshocks to form the boX.

A Wing or member 26 is adapted to cooperate With each or the yieldingmembers 22 and as there are tour of the yielding members Q2 and fourends of the shocks to told there are also tour wings 26. rlhe ends ofthe shocks which lie crossvvise are adapted to have their outer endsrest on said wings QG and at the outer edge ot' the Wings are yieldinglyheld members7 plates or parts :27 which have a relative movement andwhich are adapted to aline or cause the shoolrs to be properlyregistered. rlhe ineinbers 27 have a tongue-and-groove connection `withthe wings and iii'ieldingly 'forced outward by springs 38 or otherwise7said outward movement being limited by stops 28 held to the ,.iersurtace of each plate 2T and adapted to eng ge the outer ond ot the wingon `which the p1 27 moves. rlhe springs Q8 are located on i outsideoithe plates 27 and are interp lugs on said plates and lugs c tbe wings2G. The inner edges of the Wings 26 are substantially semi-circular andare adapted to underlap the outer edges oit the members @o outer edgesot the 5 id members 22 and with a lapping etect yieldingly hold and moreabout the shoolrs at the told so that the latter cannot sliver or breakeven should the hooks be oit cross-grained Wood. The inner ends o1 theWings are provided with recesses which receive the ends 29 oitspringpressed bolts 30. rlfhese bolts, tivo for each vving, have theirloiver ends passing through apertures in lugs 30LL on the die head, andaround said bolts are springs 30b tending normally to torce the saineoutwardly and to yieldingly hold the inner edges ot the wings 25 againstthe outer edges of the members Q9. said springs having seats in recessesor ccncaved portions in the heads ot the bolts 3G at one end. and havingseats in the lugs 30 at their other ends or in cupshaped devices itprelerred. A pluraiity o't spring clips 30C are provided each having tworetailing `lingers which are adapted to partly spur` the heu ds oit twoot the bolts 30, there being a clip tor each pairI oit bolts 3f) of eachWing.

To move the die upward and also to more the wings QG to told theshor'il-:s and iorin the sides thereof, various means may he employed.is shown. the wim )A3 are provided with lugs 31 and conne d to theseends oil the arms E are err yted bv plus 32 to a cross-head i323. theinner portion ot which is provided with an opening in vf'bioh is held atubular member -t. the latter being arranged around the central Juhumeniber 9,1 and being held to the cross-hea d 23? by means of a nut 35or in any other des ed way. Tivo linls or arms 3G are connected to eachpair ot arms 3?! at one rnd and to the die head 1'? at the other end.and said lV .lis are adapted during the upward movl` oi the crossdreadE32-l to hold the arms 2lij i such a manner as to ed between .-5.

so that in their npn Yrd folding inove u. i g endl-ic elle sani@ er) nlmo properly about the outer edge of the plates or members 22 during thefolding operation. rllhe cross-head 3S has outwardly extending arms 37,the outer portions ol which are pivotally connected by tubular pins 38to arms or links 39. The pins 38 are held to guide blocks l0 which areadapted to move vertically in guides Mlfl forming a part oit a boxlikestructure 42, the said parts serving to prevent any rotary movement otthe die as the same is moved upward. The lower ends of the links or rods3S) are connected to arms Ll?) and these arms are pivotally held to ashaft fil- These arms are connected to be operated by an arm l5 which isconnected to a link or rod elli. The rod i-6 is connected at its lowerend `to an arm i7, and said arm is pivoted at Li8 to the machine frame,said rod LlG being provided with a turnbuckle i9 by which the latter maybe adjusted. rlhe arm 47 is provided with a trundle 50 which is adaptedto be operated by a cam 51 arranged on the drive shaft 52. The die head17 has downwardly extending portions which are connected by tubular pinsor thimbles to the upper ends of links or rods T he lower ends of therods are connected to arms 55 and these arms are operat-ed 'through anarm 5G which extends outwardly and moves about the shaft llll as apivot. The arms 5G is coimected to a link or rod 57, the lower end ofwhich is pivoted to an arm 58 which adapted to rock on the shaft 48. Thearm 5S like the arm Li7 is provided with a trundle 59 which is adaptedto be operated by a cam (SO, said rod 57 beingl also provided with aturnbuckle 6l by which the latter may be adjusted. lt will be evidentthat as the shaft is rotated7 the cams will operate the arms i7 and 5Sand will move rods fl-G and 57 so that the die head 17 and thecross-heaf will move in unison and at the proper time during the upwardincrement owing to the character oi the cams 5l and GO? the arms willcause the wings 26 to be moved at an angle with respect to the uppersurface ot the die, thus forcing the ends oit the shocks uiviwardly tofold the same. lnstead oit' the particular mechanism described foroperating the die, any suitable mechanism may be employed.

rlhe punch 11 has a part thereof bodily movable downward toward the dieso that the shocks may be held between the die and the punch and by thepunch and die the shocks are carried upward and during such upwardmovement folded into box form. rlhis punch l1 has a presser toot 62, ainemher (32%, and a third member Gel. The member (il is held to a headG5 and about said head is an anvil (lll which is substantiallyrectangular in i'iorm and about which the metal binding strip is formedso that its open edges extend downward as shown best in Fig. l0. Themember Gfl has yielding sides 67, the lower edges of which are providedwith ribs 68 which are adapted to be seated in grooves in the upturnedportions G9 of the body 70 of said member 64, though instead oit saidmovable sides, the said member may be solid. Each side is normallypressed outward by one or more springs 7l and such outward movement islimited by one or more screws 72, the threaded portion ot which is heldin the body portion 70 of the member (Si and the head of which is seatedin a bushing or cup-shaped cap 73 which may be spun into an opening ineach wing or side 67 so that said sides may be permitted to yieldproperly under the pressure or the plates 27 and die wings or members 2Gwhen the latter are forced to the position shown in F ig. 10. The screws72 may be locked from turning, F ig. 15a, by a ball 73 which is arrangedto engage the inner portions of two ot th-e adjacent screws 72, saidball being forced inwardly by a screw 73D at the same time forcing theunthreaded ends of the screws 72 against the unthreaded walls 73C of thebody 70. The member (il of thel punch has a relatively slightup-and-down movement, while the member 63 and presser toot 62 movetoward the die and then upward again7 although said presser foot 62 hasa relative movement with respect to said member G3. This presser foot(32 has a body 74 substantially rectangular in form and while somewhatsmaller corresponds to the shape or the bottom o't the box or basket tobe made and has a tubular stem 7 5 which is adapted to slide within thetube 7G, there being a key or wedge 77 which passes through a slot 78 inthe stem 75 and serves to draw the member (33 up tight on the taperedend of the tube 76. rIhe presser i'oot serves as a stripper l'or themember G3 to keep the bent part of the shooks from wrapping around oradhering to said member when the latter comes out of the box whenformed. rl"he presser foot is normally forced downward by springs 7 9arranged.between the upper surface oi the body 7l or" said foot and ailauge at the upper portion of the member (lh the said springs beingarranged around rods projecting upward from the presser foot and whichserve to hold the springs in position. The member 63 or' the punch orplunger has a tapered opening centrally thereof which fits upon thetapered end ot' the tube or guide 7 G. The tubes 76 and 80 extend upwardthrough a part 8l of the machine frame and at the upper end of the tube76 is a yoke 82 which is rigidly held to the tube 7G and is adapted tohave a vertical reciprocatory movement imparted thereto by means oflevers 83 or othen wise so that the member 63 with the presser toot 62may be forced down to meet the die soY and to engage the shocks and thento move upwardly with the die again carrying the shocks therewith. 11spreviously stated, the shoolrs lie crosswise in the holder 10 so thatone will be at a higher level than the other in order that any diterencein their lengths will not cause the top shook to spring the one beneathit down so tar that the latter will be away from its registered positionin the fixed grippers 14. rlhese shooks may be moved from the iixedgrippers without breaking the ends thereoi'r'. rhe die should be closedto approximately thirty degrees, and said die in its upward movementpasses through the holder 10 and during such movement the ends of theshooks will draw in and will be 'treed from the grippers, it beingunderstood that the punch coperates with the die at this time. rlhe diecan continue to rise and should there be any tendency for the shocks toslip more to one side than the other, a little tension bar, not shown,extending out of the die may be employed to hold the shocks between itand the punch to keep the shocks from moving or revolving. The tube Shas a collar or head Se against which rests the upper end et a spring85, the lower end of said spring resting against apart 86 ot the frameportion 81. rlhe spring 85 serves to force the ubc S0 and the anvil Gupwardly when released as will presently be described.

ils the shocks are folded into box form as shown in Fig. 10, the upperedges therei are received in the open portion of a substantiallyrectangular metal binding substantially *e-shaped in cross-section whichis held and supported in any suitable way about the anvil 66, theparticular construction ot anvii and the means whereby the strip orstrips are formed rectangularly thereabout, not forming a part of thepresent invention, may be of any desired construction or may be such asdisclosed in the application herein reif-erred to. After the metalbinding has received the upper edges ot the boX form, suitable clenchermechanism, as 87, may be employed to clench or crimp the narrow metalbinding about the edges ot' the box form. As one means, l provide levers8S which may be pivoted, at 89, to a head 90 or part of the trame, and

- at their lower ends, said levers carry adinstable presser or clencherjaws 91. rThe upper ends of these levers 88 may be held by springs andhave a toggle connection with the sleeve 92 by means of links 93, saidlinks being kept from coming out by screws 93a. The sleeve isindependently movable upon thc tube 80 by means of levers 94 orotherwise so that at the proper time the metal strip or strips about theanvil is forced into locking engagement with the boit form.

After the strip is clenched about the box body, the die is lowered andas the die is lowered the box or basket is carried therewith and may bedeposited into four corner holding members 94e, Fig. 1, substantiallyf-shaped in torni and mounted in the holder 10, or the boxes may beotherwise disposed ot' as preferred. To assist in removing the bei; orbasket from the punch, I provide suction means. This suction means maybe accomplished in any suitable manner. As shown, the suction pad 18which is held by means or the plate 19 and tubular screw 20 against thedie head 1? is adapted to tit snugly against the bottom ot the basketand suction is created within the tube 21 in such4 a way and at such atime that the basket will be caused to be held to the bottom of the dieand with the assistance of the presser toot 62, the said basket whencompleted will be forced or stripped from the punch. The tubular screwhas radial slots 95 which are adapted to register with slots 96 in theplate 19 so that when suction is created within the tube 21, air may bedrawn through said slots 96 to create suilicient suction to hold the boxshocks to the die bottom and said suction should be destroyed at theproper time to adapt the box to be removed automatically or otherwise.The tube 21 is provided with an opening 97 and this opening is adaptedto register with an opening 98 in a tube 341 arranged around said tube91. rlhe tubes 21 and 3-1 are movable in a tubular part 99 of themachine frame. This tubular part 99 has an extension 100 to which may beconnected an exhaust pump and within the member 99 around the tube 3d ischamber 101. This chamber 101 is adapted topbe placed into communicationwith the openings 97 and 98 to canse suction about the box or boXmaterial as shown in Fig. 3. The suction or vacuum is adapted to bedestroyed by a relative movement between the tubes 91 and 34 as shown inFig. 2, and a small opening 101a in a plug 102 located in the bottom otthe tube 21, which opening is of such a size as will not injuriouslyaffect the suction means while in operation and while the ports oropenings 97 and 9S are in alinement but which will destroy any vacuum inthe tube 21 as soon as the suction means is cut orf, there being anadjustable thimble or sleeve 102a provided whereby the time when thesuction is destroy-ed through the opening 98 may be properly timed.lnstead ot' the ports and the parts as shown, any suitable means may beemployed to create or destroy the suction or vacuum.

There are two hooks or catches 1055 and 1011 which are located adjacentto the punch and which are supported adjacent to` the anvil about whichthe metal binding whether a single or double strip or two strips isadapted to be termed to substantially the shape of the open end of thebox form. These hooks are adapted to sustain and hold the ends of thebinding metal, the hook or catch 103 being yielding and the hook orcatch 101- being normally fixed. There may be as many of these hooks ofeither the yielding or fixed kind or both kinds' as desired. The hook103 has an elongated shank portion 105 which is adapted to fit into acircular socket 106 and is pivoted, at 107, at the inner portion of thesocket 106 to adapt the outer or hooked end 108 to move up-and-down. Thehooked end 108 has a lip 109 which is adapted to engage under one edgeof the metal binding and the shank 105 of the device is provided with aslot 110 which is adapted to form a seat for a part 111 of a spring 112.The socket piece 106 is cut away to permit proper up-anddown movement ofthe hook 10o and is held therein against outward movement byone end of aplate which is held in place by a fiat screw or otherwise. At the innerend the socket piece is adapted to abut against the head of a screw 113by which the position of the socket 106 may be determined. As one freeend of the metal binding is forced about the anvil, it will raise thehooked end 108 to pass by the same and when against the anvil the end108 will be forced downward and the lip 109 will engage under the loweredge of the binding. The other free end of the binding during thefolding operation about the anvil is adapted to have its free end forceddownward by a cam 114, Figs. 16 and 20, located on one of the clencherlevers S8 in substantially the same manner as described in theapplication herein referred to, the free end of the strip being forceddown far enough to pass under the free end of the binding held by thehook 103 and to enter a recess 115 between the anvil and the lip 116 ofthe end 117 of the hook or catch 101. At this time the end of thebinding will overlap and when the plunger mechanism has been operated asalready described, the 'compression of the metal binding to grip theupper edges of the box form will cause the edge held by the lip 116 topass therefrom so that the completed box may be stripped from the punchwithout the hook 10e or the hook 103 interfering in any way with themetal binding. The hook 1041- has a shank 118 and is held in a squarebox 119. This box fits a similarly shaped socket located over the formeror anvil 66 and said box is adjusted outwardly by means of a screw 120.rThe box 119 has one edge thereof provided with a tapered recess andadapted to engage this recess is a tapered screw 121 by which the box isheld against removal. The metal binding is thus held in position toreceive the upper edge of the box form during the upward movement of thedie and punch, and

as soon as the binding has been clenched to the box form and the jaws 91receded from their clenched position, the die is lowered.

The die waits for the box and the punch and die go down together, thedie wings 26 remaining folded around the same during the descent of thedie. This condition exists until the die bottom is down and the box orbasket .is lodged in the holding members 9st, after which the wingsquickly open fiat. This folded up relation of the wings in the descentassists materially in stripping the box from the punch.

If the machine is automatic the turret or holder 10 carries the box orbasket to an ejector. Y

It is desirable that the four folding wings or members of the die beindependently adjustable so that they will coperate properly withrelation to the punch and the anvil.. This means of adjustment may be ofany suitable kind. As shown, Figs. 5 to T, the arms are arranged inpairs and spaced apart at their upper ends by a spool 122 and are heldin such spaced position by a screw 123, a tube 121 serving as a shaft orpivot for connecting the arms 32 to the wings 26. The links 36, therebeing two for each wing, are held to a spool or spacer 125. rThe spacer125 has threaded portions 126 on which are spanner nutsV 127, the latterhaving recesses to permit the shank of a screw 12S to engage the same,the shank of the screw passing into one of the links 36 thus preventingthe nuts from unscrewing. The spool or spacer oscillates upon aneccentric pin or shaft 129 which is held against rotary movement in thearms This shaft 129 has one end provided with a nut 130 and its otherend with a cap or collar 131. This cap or collar is pro-vided with aplurality of openings 132 in one of which is adapted to pass a screw133, the shank of which is screw-threaded and engages an aperture in oneof the arms 32, thus the shaft or pin 129 may be variously positionedsothat the arms or links 32 may be adjusted relatively to the die.head17 in order that the wings may have the right relation to the anvil andto be moved for adjustment independently of each other. The eccentricshaft or pin 129 may have an oil passage 1.34 whereby the spool orspacer 125 may be properly lubricated.

If it is desired to remove the anvil 66 and head 65 for repairs or otherpurposes, this may be done very readily by releasing the screws 135which hold the tube S0 to the sleeve 136 which supports the anvil. Thelower end of the tube is threaded and engaging said threaded end is aSpanner nut 131. By removing the pin 77, the presser foot may be removedand the punch' 63 may be removed which will release the punch member 611so that the anvil may be removed and afterward reinserted in the machineas d esired.

The sleeve 13S serves as a bearing for the reciprocatory tube 135, butis intended more particularly for a stop for the upward return of theanvil head (if). This stop being adjustable, allows the wire rim ormetal bindingI which is held on the anvil and not yet clenched on thebox body to bear di Pferent vertical relations to the clenching jaws 91and thus affects the elenching of the binding either high or low on theside of the rim or binding itself. This allows of easy adjustment to`cause the jaws 91 to clench the lower edge only of the U-shaped metalrim on to the wood shooks leaving the npper or top portion of thesection of the shaped binding and wood unfiattened. By this means, anovel method of making a very strong and practical fastening of themetal to the wood is secured. rEhe shape of this fastening is on theprinciple of the engagement of a dovetail, as at 1882, Fig. 10, andallows the wood to shrink awry from the metal and yet not pull out ofthe dovetail in the metal. Wooden shocks, it might be mentioned, have tobe worked in a damp state and always shrink thereafter, especially whenmade of sweet gum. The adjustment of the sleeve 138 is secured byturning the same by means of spanner slots 139 and then setting up thelock nut 1&0, said sleeve 138 being threaded at its upper end 14:1 andengaging a threaded bore 1&2

in the frame 90. The lower end or stop end 143 engages with a portion1th of the head G5 for the anvil 66, there being a clearance space toallow adjustment between the head and the stop end 14: rThe head {35 andthe anvil are moved to its lowered position against the tension of thespring 85 by the sleeve 92 to place the anvil in alinement with thefolding jaws of the metal bending mechanism, the anvil being raised bythe spring 85 as the sleeve is elerated to move the clenching` levers S8and jaws 91 to clench the binding to the box forni.

l/Vhile the anvil and some of the parts cooperating therewith are shownin more or less detail, these parts as well as the mechanism for bendingthe metal rim or binding about the anvil relate more particuf larly tometal bending and form only in a general way or broadly a part of theinvention of this application. complete descriptien, therefore, et suchparts is thought unnecessary. lt might be well to mention however, thatthe head G5 has ledges 111-5 which serve to keep thoshooks when foldedinto box forni from pushing the rim or binding up off the anvil Thecasting 1&6, lfig. 10,

has bosses 147, if ig. 141;, at its four corners and said bosses haveapertures in. which areI pivot pins 1-1-8 for the folders of the bendingmechanism to swing around. rthere are also bending edges 1li/E), iig.16, adapted to cooperate with the folding means to form the corners ofthe rim or binding.

All of the hollow pins may be made to serve as oil reservoirs by closingthe ends thereof with plugs 150, one of which is provided with a vent oroil opening. The pins 1%, Fig. 5, are split back to receive tapered pinswhich, when the latter are driven in, spread the ends of said pinsmaking a tight fit in the ears of the wings 26. One of tho plu 150 ofeach pin may have a vent or oil opening 1:51, the vent or oil. openingof the plug being positioned so that the hollow pi n or shaft may befilled about two-thirds full of oil. The plugs may be removed byinserting a rod through the opening 151 to drive out the solid plug andthen the vented plug may be driven out from the open end of the pin.rljhe eccentric pins 134imay have threaded plugs in their ends, one plugof each pin having an oil hole and the pins 31triay also have similar orother plugs as well as the pins 89 of the clencher levers, there beingan outlet opening in each instance for the oil to pass to the bearings.

From the foregoing, it will be evident that oii'ective means areprovided whereby boxes or baskets of various sizes may be made and ametal binding applied; that simple means is irovided wherebycross-grained shocks may be utilized and folded without breaking at thepoint of fold; that simple means is provided whereby irregularities inthe lengths and thickness of the shocks may be compensated for; thateffective die and punch mechanism is provided in which the parts areproperly adjustable with relation to each other; that said parts arereadily accessible for repairs or for other purposes; that simple andetlicient pneumatic means is provided to assist in stripping` the boxwhen completed from the punch; and that said mechanism is of such acharacter that parts thereof are adapted for use in connection with anentirely automatic machine or in a machine which is only partlyautomatic or of a h and-opera tive kind.
